Answer:
Step-by-step explanation:
Given that the number of a certain type of bacteria increases continuously at a rate proportional to the number present.
Initial population = 150
Hence equation for population P would be
where t = time in hours
When t=5, P = 450
Substitute to get
k=0.2197
is P(t)
P will double when
t =3.155
Between 3rd and 4th it would double
c) Yes it doubles when 3.155 hours lapsed from the start time since t in the equation is time lapsed from start time.
